Proto Industrial Tools J1213MT500 Torque Wrench

The Proto J1213M-T500 13 mm full-polish 12-point metric combination wrench is a chrome-plated alloy steel hand tool designed for metric fasteners around 13 mm. At 8 inches long overall and weighing about 0.21 lb, it balances reach and maneuverability for automotive and mechanical maintenance. The open end features Anti-Slip Design (ASD) to help grip stubborn fasteners, while the box end uses Proto’s TorquePlus system to improve engagement in tight spaces and reduce cam-out. This 12-point design provides more contact surfaces than standard 6-point wrenches, enabling easier alignment in recessed fasteners and enabling both quick turning and high-torque tightening when paired with the appropriate fastener. The tool is part of Proto Industrial Tools’ line and is commonly used in automotive repair, equipment maintenance, and general mechanical assembly where 13 mm metric hardware is typical.
